Electrical Earthing

Soil Resistivity

Soil resistivity testing is not only a key component to a successful electrical earthing system design, but is crucial in 'right-sizing' your design so that the earth is matched to the soil in which it's going to be installed.

Lightning Safety

Risk assessments undertaken to ensure lightning protection and electrical earthing systems can be safely integrated. High Frequency software is used to model the effects of a lightning stroke to structure, equipment, tank or substation.

Electrical Earthing System Design to EN 50522

GreyMatters takes "Electrical Earthing System Design" what is traditionally a "black art" and through measurement, analysis, constructional simulation software (CDEGS) and a lot of "grey matter"... translates electrical earthing system design issues into simple to understand visual images and risk maps, identifying where the risks really lie.
GreyMatters designs technically secure safety electrical earthing solutions (grounding systems) for voltages between 1kV - 765kV in order to meet the recently updated international standards and regulatory obligations. BS7430

WHAT WE CAN DO FORYOU?

Electrical Earthing System Design and Simulations - Electrical Earthing Design Risk Assessment Surveys and measurements for substation or generation schemes on voltages from 1kV to 765kV are undertaken by our highly qualified engineers.

Soil Resistivity Testing -
Understanding the soil resistivity and its impact on Electrical Earthing System Design return current behaviour under fault conditions as part of the Safety Calculation requirements. Soil Resistivity Testing is not only a key component to a successful Electrical Earthing System Design, but it is crucial in 'right-sizing' your design so that the Electrical Earthing System is matched to the soil resistivity in which it's going to be installed.

Lightning Safety Studies - Risk assessment and design undertaken to ensure both the lightning protection and electrical earthing systems can be safely integrated. We use specialist High Frequency CDEGS software which allows us to model the effects of a lightning strike to a structure, piece of equipment, tank or substation.
